Your Kibana/Cloudwatch/Grafana have different timestamps, you don’t see recent logs from your application. Why is that? You may ask. Some QA reports that your application is not working/was not deployed, asking you to review the deploy process. Or even worse: asking your devops colleagues to “something went wrong” with last deployment could you check?

You login into your shell running kubectl get pods to verify timestamps update or checking Helm releases helm ls. But everything seems fine, everything deployed. CI/CD is green, all timestamps updated. But yet. QA does not see the logs. Where have they gone?
